Pann is an STO recruit. He was the first student that Clarice Willow lured into the STO. At some point in time he switched sides to join Barnabas Greeley's cell. Barnabas is Clarice's rival.
Pann is part of a botched attempt to kill Clarice by planting a bomb at the Trojan Spaceport in Caprica City. When Clarice discovers this, she goes to his home to confront him. He begs forgiveness and promises to repent the error of his ways. She says she forgives him, but will God forgive him? She answers that question by throwing a television set into his bathtub, electrocuting him. ("Retribution")
